1 2 available space against damage is protected and can be operated remotely. 1. Mobile hoist for bulky and The invention solves the problem in such a way that heavy goods or loads such as containers and 3 the wheels in on the posts near the feet Swap bodies, consisting of two pivoted wheel forks, Portals connected to longitudinal beams, the posts of which are known per se (French patent for Wheels run and on their crossbars the writing 1032859), and in the posts are adjustable lifting members are articulated, housed in unloaded directions, the linkage on the The state can be moved on its wheels and has an effect on the pivoting movement of the wheel forks. loaded state can be lowered onto its post, this arrangement arrives without sliding guides characterized in that the wheels consist of posts or wheel forks and enable the der (9) in a manner known per se in the actuating forces available at the Pfo in a simple manner Most (1) close to the feet (12) swivel-way to translate and so the decreed on the wheels Wheel forks (91) are mounted and adjust in 15 divided weight of the hoist. the post adjusting devices (71) under- In a preferred embodiment serve as are brought, the linkage (711) on the ftadga adjusting device stan built-in hydraulic cylinders, affect the pivoting movement of the leg. whose piston rods are tappet-like directly on the 2. Mobile hoist according to claim 1, act on wheel forks. In this form the characterized by rigidly installed hydraulics- *> The actuating device is very compact and the interfering cylinder (71) is used as an actuating device whose KoI- can be accommodated in the post without the benstangen (711) is immediately hindered in the interchangeability of a tappet. The wheels will Act on the wheel forks (91). Swiveled out hydraulically to move and go into the cylinders when the pressure is released »5 back again until the post feet are on the ground put on. Through pressure relief valves in> the supply line gen can ensure that a recording the load if the wheels are accidentally extended does not lead to axle breaks or the like. Furthermore, the hydraulic cylinders for the pivoting movement The invention relates to mobile lifting of the wheel forks with a hydropneumatic be equipped with suspension for bulky and heavy goods or loads. This known per se such as containers, swap bodies and the like a type of construction that in the unloaded state on wheels device on uneven ground an additional safe travel and in the loaded state on post 35 means against overloading the swiveled out wheels is lowerable. It has namely in the practical and their wheel forks. Loading and shipping company showed that in many If the hoist has a hydraulic system for BeFallen it is only required that a good, e.g. B. has a container activity of its lifting links, the Hyner or a swap body, at the place of the driving hydraulic cylinder for the swivel movement of the wheel equipment, z. B. a flatbed, to take off, to set down, to 40 forks expediently received from this hydraulic system. or loaded and then put back on. feeds. Thus a hoist is known which consists of two by while on the one hand the expression »in unloaded Longitudinal beam connected portals exists, the condition of which «should not exclude that the device Posts run on wheels and not with an empty container attached to their crossbars the lifting links are articulated, and at which the wheel 45 could be moved, for eme such a load which spring in automatically under load (USA.Patent is minimal, on the other hand there is extraordinary document 1 772 734). With this type of lowering, the advantageous possibility of attaching the device to its portal loaded hoist can post the hoist with a fixed castor platform, roller pallet During the load pick-up on uneven ground or the like. To be coupled and loaded on this one roll away before its post feet are firmly in place. 50 container to move. Only the drive is staged. overall to be interpreted a little stronger. There are also details and advantages of the invention in hoists of this type can ι, the wheels by means of attached to the outside of the post in the following carried out on an exemplary embodiment, Manually operated adjusting device explained, which is shown in the drawing. gen, whose linkage act on the wheel bearings, in 55 In this shows their distance from the post feet - and thus F i g. 1 in a perspective view of a portal against the ground - to adjust. Capability of the lift truck according to the invention with a raised load, limitation in the area of application to and retracted fixed castor platform and in enlarged lifting, holding and lowering of loads and decaying scale in partial representations,

Since the dead weight of the F i g. 1 shows a frame construction of the mobile Lifting equipment is relatively small, a lifting equipment can be made of light, but sufficient sifache Wheel suspensions and solid rubber tires made of safety-designed steel tubes. Two from post 1 be used. 65 and a transverse spar 2 formed portals are with one- The invention is based on the object, one another by two longitudinal beams, each consisting of two pipe hoists of the type described at the outset to be strapped out in this way 3,3 'with connecting diagonal struts 4, that the adjusting devices are connected despite the small amount.
